In this fast world, fast food has become an important part of our diets. Its convenience, affordability, and availability have made it an easy option for millions of people around the globe. As the usage of fast food rises, it is important to know about its impact on our health.
What is fast food?
Fast food means all the foods that are prepared and served quickly, mainly at restaurants and takeaway outlets. These are designed to be prepared in less time. The concept of these foods have been known for centuries, but it gained popularity in the mid-20th century. Fast food companies offer a menu with items that are usually high in calories, fats, and sugars.
Some common examples of fast food include:
- Burgers and Fries: This combination contains high amounts of calories and unhealthy fats. A normal cheeseburger with fries contains approximately 800 calories.
- Pizza: It is often loaded with cheese, processed meats, and refined flour. Only one slice of pizza has approximately 300 calories.
- Fried Chicken: A single piece of fried chicken approximately contains more than 400 calories.
- Sugary Drinks and Desserts: Sodas, milkshakes, and desserts like ice cream are commonly served with fast food, which increase the amounts of sugar and calories. A large soda contains over 200 calories.
The nutritional value of fast food is poor. Fast foods are high in fats, sugars, sodium, and refined carbohydrates. While low-saturated fats include fiber, vitamins, and minerals.
